Explanation:
n2=5
n1=2
no of spectral line
= (n2-n1)(n2-n1+1)/2
= (5-2)(5-2+1)/2
= 3*4/2
=12/2
=6

Answer:
15 spectral lines
EXPLAINATION:
The e can jump from 7 to 6,5,4,3,2; from 6 to 5,4,3,2; from 5 to 4,3,2; from 4 to 3,2; from 3 to 2. For each transition we will observe a line so the total no. of lines will be 15.
